No where do you say _why_ building this as a module is a good idea.
Yes, we discussed this before and this is actually an general question.
Main advantages are:
- Flexibility and Maintainability, allows for dynamic loading and
unloading of modules at runtime without the need to recompile and
restart the kernel, for example fixing iocost CVE in our production
environment.
- Kernel Size and Resource Usage, modules are loaded only when their
specific functionality is required.
Thanks,

Why do this at all?
